Swimming fins are one of the most recommended accessories for swim training. They allow you to work on your kick, providing resistance to tone and strengthen the muscles of the abdomen, legs and ankles. There are various formats of fins for the practice and perfection of different styles and intensities. The shorter fins are designed to work at a high heart rate with a low physical load. The longer fins, on the other hand, allow greater movement in the water, which results in greater muscular exertion at a lower heart rate as the repetition of the kick is slower than with the short fins.
